HARROW.

SPECIFICATION forming part of Letters Patent No. 346,315, dated July 27, 1885.

Application filed November 24, 1885. Serial No. 183,849. (No model.)

To all whom, it may concern:

Be it known that we, EDMUND D. REYNOLDS and OLIVER B. RnYNoLDs, citizens of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Harrows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a plan View of a harrow embodying our improvements. Fig. 2 represents a side elevation of the same. Fig. 3 is detail in perspective showing one of the arms with the teeth secured therein. Fig. 4 is a sectional view of Fig. 3. Fig. 5 represents views of one of the rear teeth, 0, and the means for securing the same. Fig. 6 represents the means for detachably securing the rock-shaft. Fig. 7 shows the latching-lever and means for securing the same.

Our invention relates to thatclass of harrows having gangs of teeth and carrying a drivers seat; and the same consists in the construction and combination of devices, which we will hereinafter fully describe, and point out in the claims.

To enable others skilled in the art to which our invention appertains to make and use the same,we will now describe its construction and the manner in which we have carried it out.

In the said drawings, A represents a single harrowbeam having a series of arms, B, secured thereto and carrying the teeth 0 and D in a manner we will describe. The arms 13 are preferably bifurcated or slotted nearly their entire length, their forward ends being perforated to receive bolts (1, which pass upward through the beam and through plates 1) upon the upper surface of the beam, to which they may be riveted or otherwise secured.

To securely hold the arms B in contact with the under surface of the beam I employ another series of bolts, 0, provided with flattened portions 0, which fit into the slotted portion of the arms 13, and are rigidly held therein by short pins or rivets d. (Sec Figs. 2, 3, and 4,.) The front row of teeth, 0, engage and are firmly held within the slotted portions of the arms by rivets d, which pass transversely through the arms and through the front portion of said teeth, the upper edges or backs of the teeth bearing against the lower ends of the bolts 0, thereby preventing upward motion. At the same time this arrangement of the teeth greatly strengthens and braces the arms 13, while the said teeth themselves are braced by being secured between the sides of said arms. The rear series of teeth are bolted to the arms by rivets d in a manner similar to the front teeth, and are prevented from upward movement by bearing against pins d, which pass through the rear of said arms.

A harrow when constructed as described can not only be made cheaper, but is superior to many of those now in use, inasmuch as fewer pieces are employed, and the several parts are firmly united together, thereby giving increased strength and rigidity to the working parts of the device, and also,by employing but a single beam, all danger of clods or rubbish clogging beneath the ordinary rear beam is obviated, while in our case these obstructions will pass between or over the rear portion of the teeth. A metal plate, E, is secured to the beam A, and is provided with an eye, 0, in which is pivotally secured one end of a rock-shaft, F, the said rock-shaft being firmly attached to the pole G and pole-stub G, as shown in Fig. 1. The opposite end of the rock-shaft F is mounted in the hook -shaped end f of a metal plate, H, the forward end of said plate being bent upward and terminating in a pintle,f, upon which a swinging plate, 11, is mounted, the rear portion of said plate being bent downward, resting upon the plate H, the end of the rock-shaft being confined between this bent end and the hook-shaped end of the plate H, thereby enabling us to readily detach from the beam the rock-shaft and withit the pole and pole-stub, and accomplish this important feature without the removing of a single bolt, this itself being an import-ant feature,as it is obvious the device may be taken to pieces or put together with but little trouble or inconvenience.

To secure the swinging plate in its proper position and prevent it from having too great movement I. employ a staple, H,which straddles the plates H H, and is provided with a draft attachment, I.

swinging lever, 11'', which is adapted to bear against the side of the plate H, thereby retaining the said plate in its proper position and securely holding the rock-shaft within its bearings. To the rock-shaft is securely bolted the pole-frame, consisting of braces h h h, the brace hpassing under and supporting the pole and pole-stub, and the brace h being secured to the side of the pole-stub. Above the brace h, and secured to the pole and polestub, is a tie-plate, h, this plate-,the brace h, and rock-shaft G being perforated at 3 with a View to securing lateral adjustment to the pole toward and from the pole-stub. To the outer end of the brace h is secured a suitable The notched latchingbar K,which adjusts the position of the beam A and teeth B and O, is loosely attached to a U-shaped bar, it, which is held against the lower face of the beam A by a plate, and securing-bolts 70.. It will be observed the forward end of the bar 70 has a slight upward inclination,while one of its side arms is extended and bent upward to form a lip, 5, which engages the rear portion of the beam. This construction effectively prevents the liability of the bark workingloose or having a longitudinal movement, and also permits the latching-bar to be swung around against the beam and out of the way when being packed for transportation. A longitudinal slot, 6, is formed in the pole-stub, and through the said slot passes the free end of the latching-bar, it being retained in its adjusted position by the notches engaging a transverse pin, 7, as shown in Figs. 1 and 2. The polestud also carries a casting, 8, in which the standard 9, that carries the seat 10, is detachably secured. It is now manifest the several parts of the harrow are readily detacha- I ble. The pole-stub and pole with its series of braces and rock-shaft are disconnected with the beam, and the seat-standard and seat removed from the pole-stub, thereby enabling the entire device to be packed in a comparatively small space. Certain of the plates 1) are extended and formed with eyes, as shown at '12, and to the eyes thus formed are secured curved rods 13, their lower ends being bolted to a transverse board or levelcr, M, located slightly in the rear of the harrow-teeth, and to this board M is attached, by means of a loose connection, 14, a beam, N, arranged slightly above and running parallel with the board M. The beam N carries a series of teeth, 0, arranged diagonal to the line of draft, and these teeth have a lateral adjustment for a purpose we will now describe.

To better definethis feature of our improvements, we will now minutely describe the several devices, whereby this adjustment is accomplished. It will first be observed the inner end of the teeth 0 are curved, and are adapted to fitwithin a correspondiugly-curved portion formed in the rear of a series of blocks, 15, the front faces of which are provided with lips or flanges 16, which pass upon the sides of the beam N, and are thereby prevented from turning. Suitable bolts, 17, pass through the beam N, the block 15, and thence through elongated slots formed in the curved ends of the teeth 0, and may be secured by suitable nuts and washers. From this description it is manifest the angle-of the teeth 0 with relation to the line of draft may be changed by loosening the securing-nuts and moving the teeth in the desired direction. Whilethese teeth 0 have a lateral adjustment, it is necessary that they should be prevented from vertical movement, and this latter object we accomplish by means of flanges 18 on the rear or curved side of the blocks, which confine the curved ends of the teeth between them. One of the curved rods 13 carries a rack-segment, 19, to which is pivoted the lower end of a lever, B, provided with suitable means for engaging the rack, and the bar N has a standard, 1 projecting from its upper side, which is attached to the lever R by means of a connecting-bar, S. By this arrangement of parts it is evident the teeth 0 may be forced deeper into the ground, or be raised entirely out of the same, this being left to the option of the operator.

Having thus described our invention, what we claim as new, and desire to secure by LettersIatent, is-

1. In a harrow, a single beam, A, in combination with a series of slotted arms bolted to saidv beam and projecting rearwardly, and a double series of teeth or blades supported and braced within the slotted portion of said arms, substantially as herein described.
